Wideband Current Probe for Oscilloscopes
Hioki flat bandwidth current probes are best-in-class current sensors for use with Memory HiCorders and high performance oscilloscopes. The 3274 supports wide DC to 10 MHz bandwidth signals and 150 A of continuous high input, letting you capture transient current signals from switching power supplies, inverters, and motor controllers. The probe is designed with a high permeability magnetic shield to reduce the effects of electric fields, making it ideal for measuring low currents or nearby high-current lines.
